A good stock analysis site should make it easy to move from a broad idea to a specific, testable question. Useful sites expose their data, explain their metrics and let you inspect the evidence behind a summary score or chart.
Check how far back the history goes and whether the data source is clearly described.
Look for more than one summary metric. Strong research shows distributions and underlying observations.
Some sites are strongest in fundamentals, others in charts, screening or historical seasonality.
Definitions and formulas matter. You should know what a “win rate” or “average return” actually means.
A research workflow should make comparisons fast enough that you can test alternatives rather than settle for the first result.
Free access can be valuable when the core data and calculations are available without a subscription wall.
